This is a good article. Follow the link for more information. Douglas re-purposed one screen to demonstrate portraying other information to the user, such as the state of a noughts and crosses game. After the game served its purpose, it tic tac toe board printable pdf discarded on the original hardware but later successfully reconstructed.

Under some definitions, it thus may qualify as the first video game, though other definitions exclude it due to its lack of moving or real-time updating graphics. Like other early video games, after serving Douglas’s purpose, the game was discarded. University of Cambridge’s Mathematical Laboratory by special permission, as the EDSAC could not be moved, and both the computer and the game were only intended for academic research purposes.

This article describes five of them: state-space complexity, game tree size, decision complexity, game-tree complexity, and computational complexity. A to move can be labelled “player A wins” if any successor position is a win for A, or labelled “player B wins” if all successor positions are wins for B, or labelled “draw” if all successor positions are either drawn or wins for B. And correspondingly for positions with B to move.

A full-width tree includes all nodes at each depth. It will be upper-bounded by the complexities of each individual algorithm for the family of games. There are three states for each cell and nine cells. This count includes many illegal positions, such as a position with five crosses and no noughts, or a position in which both players have a row of three. A more careful count, removing these illegal positions, gives 5,478. And when rotations and reflections of positions are considered identical, there are only 765 essentially different positions.

A simple upper bound for the size of the game tree is 9! There are nine positions for the first move, eight for the second, and so on. This includes illegal games that continue after one side has won. A more careful count gives 255,168 possible games.

When rotations and reflections of positions are considered the same, there are only 26,830 possible games. The bridge table can be regarded as having one slot for each player and trick to play a card in, which corresponds to board size 52. Game-tree complexity is a very weak upper bound: 13! 4 players regardless of legality. Note that the last 4 plies are always forced moves with branching factor 1.
